On Access points and streaming video via wifi
We are currently planning a party for a friend and I wanted to load some videos on a server then hook it up with these powerful outdoor AP (its a big hotel) then have all the guests log in and stream the video(via XMBC or MediaTomb) to their devices (720p and higher video mark you) I have several questions 1. Do these Access Points have a maximum no of users who can be connected? 2. Do they have a maximum bandwith? 3. What are the disadvantages of these idea and what should I watch out for? I haven't made a decision on which to buy so go ahead and suggest whatever you think has the highest no of simultaneous users and bandwith
More details please: - which brand of access points are you talking about? - how many users are you planning for? - what devices are the users carrying? - how far are they going to be from the access points? - do you have clear line of sight between the APs and the users? - what is the link speed between the video server and the access points? - what are the specs of the video server - CPU / RAM? - what else is going on in that area - other guests, other WLANs, etc? A lot of things need to be known or planned for to ensure perfect delivery. Kind regards, Bernard On Mon, Dec 9, 2013 at 11:02 PM, Silas Savali <dzez2003@gmail.com> wrote:

I have several questions
1. Do these Access Points have a maximum no of users who can be connected?
Maximum number of users per AP is determined by the IP address space being used. If your DHCP server is configured for a /24 subnet, then of course you have a maximum limit of 253 users, because the AP takes one IP.
1. Do they have a maximum bandwidth?
Well, that sounds obvious to me. When you buy an AP, they say the Wireless
speed - 54Mbps/150Mbps/300Mbps... and you never really achieve that max speed....
1. What are the disadvantages of these idea and what should I watch out for?
Not having implemented any such infrastructure, I have no clue as to what the cons would be.
However, your APs must be able to support the throughput that you expect. -- Best regards, Odhiambo WASHINGTON, Nairobi,KE +254733744121/+254722743223 "I can't hear you -- I'm using the scrambler."
Thanks alot. The part for maximum no. of users was the ones that was giving me a headache. On 11 December 2013 16:16, Odhiambo Washington <odhiambo@gmail.com> wrote:

As you embark on the exercise, I would advise on the following: - do some planning and investigation to ensure you look at all the bottlenecks and possible sources of issues (congestion, interference, capacity of APs etc) - it is important to do a test a few days in advance.Try to simulate the load that the network will have to carry on D-Day. You can use a couple of tablet PCs and also do concurrent downloads using a download manager to verify that the infrastructure can take the load. - do not ignore the obvious - UPS for the APs and servers, traffic control with respect to competing uses - e.g. torrents, plan B.. Looks like an interesting event. Have a lot of fun! Kind regards, Bernard On Wed, Dec 11, 2013 at 5:42 PM, Silas Savali <dzez2003@gmail.com> wrote:

Access points have a theoretical maximum based on the modulation implemented. The standard 802.11 bg has a maximum 32 users connected concurrently but the number may vary depending on data rate requirements of each connected user. I have seen others talk about about 100+ concurrent users but in real world cases its not possible with the kind of bandwidths we utilize.

WiFi R&D has progressed so much, you will be shocked. Innovations like beamforming, bandsteering, dynamic interference rejection, dynamic channel selection, adaptive antennas, etc have taken WiFi performance to a new level all together. Vendors like Ruckus and Xirrus have taken huge strides in the area of dense wifi deployments, with mid-level APs for under USD 2,000 that do 500 concurrent users without breaking a sweat. When doing high-performance WiFi, SOHO APs like Linksys and D-Link simply cannot do the job. One must look into purpose-built products that can get the job done. At the end of the day, it comes down to the amount of money you are willing to spend (and of course, the laws of physics which must be obeyed) Kind regards, Bernard On Thu, Dec 12, 2013 at 10:38 AM, Odhiambo Washington <odhiambo@gmail.com>wrote:

Typically, this is what you can do 1. A single mp4 video stream at 720p will need 3-5mbps depending on how it's encoded. So your network needs to be able to provide this to every user (especially if you want them to watch simultaneously). So if you'd like 100 simultaneous people, you need 300mbps available. This is realistically not possible on a single AP. 2. 802.11n will do up to 300mbps with the best conditions (maximum modulation, and everyone with an 802.11n device eg iPads. In the real world this is usually not possible - especially when you have walls etc as you've indicated. Those will severely affect your signals & throughputs. Note that the maximum throughput from the AP is also dependant on the slowest user on your network - so one user with a bad signal affects overall performance of the whole AP. 3. You're better off deploying a few 802.11n APs ... connected by cable. That way you can get more throughput overall into your network (say 100mb x N) & can place them also so you have the best signal levels to all users, so all users are on high modulations. Your other problem is that realistically though vendors may tell you everything - most WiFi chipsets still only support up to 50 users per AP without falling over. So build your network with that in mind. 4. Also explore encoding at different bitrates. You only need 720p on a big screen really. For smaller screens eg tablets & smartphones, you can get away with a much smaller bitrate stream & still have high quality. You may only need 700kbps to 1.5mbps per stream ... You can play with multicast if your end-user device/app supports. But chances are you're just thinking of embedding the stream in a website/page ?

+1 Thanks, Riyaz. Now with the narrative I've seen here, I wonder if one day some guy decides to set his APs to draft-N/ac without backwards compat and escape the wrath of mgmnt:)
From this: "Note that the maximum throughput from the AP is also dependant on the slowest user on your network - so one user with a bad signal affects overall performance of the whole AP."

Vendors will usually recommend to you to shut down 802.11b these days - and keep running 11g/11n only. Especially in a situation you need high capacities eg public wifi, events etc. However, note there's also more clever radio/antenna algorithms that different vendors apply that help this situation. This problem is probably smaller in a general purpose environment compared to torrentors - if you're running good new APs. That will usually kill your 1-20mbps internet link before your AP capacities are reached - but the result to the end-users is the same - no internet !

Try a Xirrus array - it is built to do such things - period! On Fri, Dec 13, 2013 at 11:09 PM, Riyaz Bachani < riyaz.bachani@ke.wananchi.com> wrote:
Vendors will usually recommend to you to shut down 802.11b these days - and keep running 11g/11n only. Especially in a situation you need high capacities eg public wifi, events etc.
However, note there's also more clever radio/antenna algorithms that different vendors apply that help this situation. This problem is probably smaller in a general purpose environment compared to torrentors - if you're running good new APs. That will usually kill your 1-20mbps internet link before your AP capacities are reached - but the result to the end-users is the same - no internet !

@Job, how about for draft-N and AC standards? I see there are APs now doing 1300Mbps for home setup (although this is now OT coz this poster talked of outdoor ones).
